Specification of Letters Patent.

Patented Oct. 2, 191 '7.

Application filed November 26, 1915. 7 Serial No. 83,633.

To all whom it may concern:

Be it known that I, Hnnenn'r E. VAN DORN, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inCar-End Constructions; and I'do hereby declare that thefollowing is afull, clear, and exact descri tion of the same, reference being had to te accom anying drawin and to the numerals of re erence marked t ireon,which form a part of this specification.

Certain types of steel endshave in the past few years come into wide useto meet the persent severe conditions of heavily loaded cars. However,the types of cars are changing, steel construction taking the place ofwood construction, and furthermore the cars are larger and, with thesteel construction, very much heavier, and more is being required of theends. All steel ends now made are formed to produce the greateststrength for the particular type and weight involved. The steel in theend can only be pressed a certain depth for its weight'without beingfractured, and in order to. produce steel ends of sufficient strength tomeet increasin conditions, the corrugations must be ma e deeper, whichnecessitates using heavier plates.

An objection heretofore existin in the use of metal ends is the heat conuctivity of the metal which causes the end, for instance under intensesunlight, to absorb the li ht and transmit the heat to the interior 0the car. By this invention a stronger end than heretofore is roducedwithout materially increasing t e total weight of the structure, andfurthermore, due to the provision of a dead air space, a lessco-efiicient of heat conductivity is obtained.

This invention relates to what may be termed a double plate car endconstructed of metal for attachment on cars, and one of inherentlygreater strength than ty es of single ends heretofore constructed. us tothe fact that the combined depth of the corrugations in the double plateend is nearly twice that of the single plate end, and since the platesare made of lighter material, the weight of the double plate end isabout the same as that of the heavy single plate end of less strength.

It is an object therefore of this invention to provide a metal car andconstruction embracing a plurality of sheets of metal corrugated andlaid against each other and secured oneto another for attachment to theend of a car.

It is also an object of this invention to construct a car end comprisinga plurality of sheets of metal secured one to another and eachcorrugated and so disposed that the corrugations of one sheet extendinwardly within the car and those of the other sheetoutwardly from thecar with the contacting surfaces of the plates riveted one to another.to aflord substantially a unitary structure.

It is also an object of this invention to construct a car end comprisinga plurality of corrugated sheets of metal, the corru ations of eachplate extending outwardly from the surface of the plate so that theinner surfaces of the plates and corrugations lie in the same plane, andmay be secured by rivets or bolts to one another, said corrugationsbeing continuous and, if desired, horizontal on one side and vertical onthe other, or disposed in any relation to one another to reinforce eachother and extending inwardly within the car or outwardly from the car.

It is also an important object of this invention to construct a doublewalled car end having a space between its walls to afl'ord a heatinsulating space or to receive a filling of insulatin material therein.

It is furt ermore an important object of this invention to provide aunitary double end structure for cars whereby one member serves toreinforce the other and so constructed that in the event of one memberbeing already attached on the car another reinforcin member may besecured thereover, eit er on the interior or exterior of the car, toafi'ord a double plate metal car end.

It is finally an object of this invention to provide an improved type ofmetal car end structure self sustaining and capable of withstandingstresses applied on either side thereof, and not requiring auxiliaryreinforcement members within or on the exterior of the car.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

As shown in the drawings:

As shown in Figs. 1, 2, and 3, the car body is denoted as a whole by thereference numeral 1, and attached on the end thereof is a double lateend comprising an inner plate 2, having circular or concentricallarranged corrugations increasin in dept successively from the outer e geof the plate toward the middle, and another simiarly constructed outerplate 3, said plates arranged such that the inner corrugations of eachplate contact one another, as clearly shown in Fig. 3, to permitattachment thereof by rivets 4, one to another. The margins of said resective plates are bent at right angles and ie flat against one another,and are bent around the end posts of the car body 1, and secured theretoin any suitable or convenient manner to afford a ri 'd attachment ofsaid associated plates with the car.

In the form of device illustrated in Figs. 4, 5, and 6 the car body isdenoted as before by the reference, numeral 1 and a pair of innervertically di osed en plates 5 and'fi are provided, -wit their centralvertical margins riveted one to another by rivets 7, and secured on theexterior of the carover said vertically disposed corru ted plates 5 and6, are similarly corrugate lates Sand 9, which, however, are disposedorizontally fromthe car and the inner with the central connected marginsof said outer row of plates secured by rivets 10, which also extendthrough said inner plates 5 and 6, as clearly shown in Fig. 5. Thevertical row of rivets 7., which secure the central margins of saidinner lates 5 and 6, to ther also extend throng zonta exterior plates 8and 9, as clearly shown in Fig. 4. The side margins of the respectiveinner plates 5 and 6, and outer plates Sand 9, are laid flat against oneanother and bent around in right angled relation to the body or frame 1,of the car, as clear] shown in Fig. 6, and securely attached thereto inany suitable manner.

In the form of construction illustrated in Figs. 7, 8, and 9, I haveshown attached to the car body or frame 1, an inner plate 11, thecorrugations of which are disposed vertically over the entire surfacethereof, and secured on the exterior of the car flat against said innerplate 11. is another plate 12, with the corrugations thereof extendinhorizontally over the entire surface thereo and at points on saidrespective plates where the corrugations contact one another, rivets 13,are secured thereto to rigidly connect said plates one to anothersubstantially as a unitary structure. As in the constructions beforedescribed, the side margins of said plate are laid flat against oneanother and bent around the corner osts of the car body and securedthereto in any suitable manner. a

In the structure illustrated in Figs. 10 and .11, I have shown the carbody 1, as already equipped with a transversely corrugated end plate 14,although the particular construction or shape thereof is immaterial andfor the purpose of reinforcing the same, l have shown another corrugatedplate 15, mounted on the exterior thereof with rivets 16, extendingthrough said respective plates at the points. at which the corrugationscontact one another, and, al-,

though no marginal connections are shown between said lates, it isobvious that such may be provi ed if deemed necessa As shown in Fig. 15,the outer p ate denoted as a whole by the reference numeral 20, iscorrugated horizontally and inwardly relative the sheet, but outwardlyrelative the car and the inner plate 19, secured thereto is corrugatedvertically and outwardly, that is inwardly with res ect to the car. InFig. 16, the outer plate enoted by the reference numeral 21, is corruated horizontally and outwardly from. t e sheet and 7 plate 22, securedthereto is corrugated vertically and outwardly from the sheet.

. In the constructions'illustrated in Figs. 12, 13 and 14, I have showndifl'erent methods of connecting the lower margins of the plates to thecar frame. In Fig.- 12,

said horithe margin of the outer plate, denoted by the reference numeral17, is bent outwardly, and the margin of the inner plate, denoted by thereference numeral 18, is bent inwardly and each is secured independentlyto the car frame.

In Fig. 13, the construction illustrated shows the margins 17 and 18, ofthe plates laid flat against one another and .secured between the framemembers of the car body, whereas in Fig. 14, said margins 17 and 18, arelaid flat against one another'and both bent outwardly in right angledrelation and secured upon the car frame.

The operation is thought to be obvious from the description. Thecorrugations in the plates serve to greatly strengthen the same inresisting stresses applied on either surface thereof, and it is obviousthat where two plates are used the associated plates are capable ofwithstanding even more than twice that of either of the plates when usedalone. The greater rigidity of the'entire structure is due to theconnection of the two plates at the difl'erent points thereof, whichserves to distribute the stress from one late to another when stress isap lied upon either one of said plates. The d ziuble plate construction,as ointed out, may be as light or lighter in weight than the singleheavy plate construction. 1

Another important feature of the double plate end is the provision ofthe air space between the plates, which may or may not be a dead airspace, depending u on the particular type of construction, ut the space,whether filled with a material or not, in any event serves as aninsulating means to prevent rapid conduction of temperature changesthrough the car end.

Of course, while I have illustrated and described my invention for useas a car end, it is obvious from the construction described that it maybe used as well for a car side or as a part of any metallicconstruction, if desired.

I am aware that various details of construction may be varied through awide outwardly from the main surface, and with said sheets secured toone another with the corrugations thereon registering to afi'ord an airspace between said sheets.

2. A structure of the class described comprising a pair of circularlyand concentrically corrugated lates secured flat against one anotheraifor ing a plurality of circular concentric air spaces therebetween,and with means secured to and through said plates between said airspaces to hold said plates attached to one another.

3. A structure of the class described com rising concentricallycorrugated plates liaving circular corrugations, and with said plateslaid flat against one another with the corrugations registering toafford circular air spaces between said plates, and attaching meanssecured through said plates to hold the same attached at contactingpoints of said plates between said circular air spaces.

4. A structure of the class described comprising plates having curvedconcentric corrugations therein of varying depth, said plates securedfiat against one another with the corrugations in register to afiord aplurality of air spaces circular and concentric with respect to oneanother, and each of different depth, and means securing said plates oneto another.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.
